There is no coolant in Mercury IVs, it's the air cooling them and the temperature shown is CHT (cylinder head temperature) in Celsius, therefore 225 is OK for radial engine, even in good agreement with the manual.
The problems with Blenheim (I agree completely) are the too aggresive temp. damage for no apparent reason, prop pitch is weird (you have some space to fiddle between 'coarse' and 'fine', it's about 5-30 percent PP), mixture is not working as it should be, max. ceiling is ridiculously off etc etc, but it is possible to keep her cool - start your take-off run at some 200C, never exceed 250, you have to keep your RPM reasonable and you can actually climb with rads partialy closed and 220 steady with some practice. Point is that's not much like the real think flew, but it's not impossible.
